Conventions for Designation of Variants

For purposes of the present invention, in an embodiment the maturepolypeptide disclosed in SEQ ID NO: 2 is used to determine thecorresponding amino acid residue in another lipase. In anotherembodiment the mature polypeptide disclosed in SEQ ID NO: 10 is used todetermine the corresponding amino acid residue in another lipase.Positions in SEQ ID NO:2 relevant for substitution in the inventioninclude F7, F51, T143, A150, H198, N200, I202, S224, L227, V228, P229,V230, I255, T256, A257, L259, and W260. Positions in SEQ ID NO:10relevant for substitution in the invention include F7, F51, T143, A150,H198, N200, I202, S224, L227, V228, P229, V230, I255, P256, A257, L259,and W260. The amino acid sequence of another lipase is aligned with themature polypeptide disclosed in SEQ ID NO: 2 or SEQ ID NO: 10 as thecase may be, and based on the alignment, the amino acid position numbercorresponding to any amino acid residue in the mature polypeptidedisclosed in SEQ ID NO: 2 or SEQ ID NO: 10 is determined using theNeedleman-Wunsch algorithm (Needleman and Wunsch, 1970, J. Mol. Biol.48: 443-453) as implemented in the Needle program of the EMBOSS package(EMBOSS: The European Molecular Biology Open Software Suite, Rice etal., 2000, Trends Genet. 16: 276-277), preferably version 5.0.0 orlater. The parameters used are gap open penalty of 10, gap extensionpenalty of 0.5, and the EBLOSUM62 (EMBOSS version of BLOSUM62)substitution matrix.

Identification of the corresponding amino acid residue in another lipasecan be determined by an alignment of multiple polypeptide sequencesusing several computer programs including, but not limited to, MUSCLE(multiple sequence comparison by log-expectation; version 3.5 or later;Edgar, 2004, Nucleic Acids Research 32: 1792-1797), MAFFT (version 6.857or later; Katoh and Kuma, 2002, Nucleic Acids Research 30: 3059-3066;Katoh et al., 2005, Nucleic Acids Research 33: 511-518; Katoh and Toh,2007, Bioinformatics 23: 372-374; Katoh et al., 2009, Methods inMolecular Biology 537:39-64; Katoh and Toh, 2010, Bioinformatics26_1899-1900), and EMBOSS EMMA employing ClustalW (1.83 or later;Thompson et al., 1994, Nucleic Acids Research 22: 4673-4680), usingtheir respective default parameters.

When the other enzyme has diverged from the mature polypeptide of SEQ IDNO: 2 or SEQ ID NO: 10 such that traditional sequence-based comparisonfails to detect their relationship (Lindahl and Elofsson, 2000, J. Mol.Biol. 295: 613-615), other pairwise sequence comparison algorithms canbe used. Greater sensitivity in sequence-based searching can be attainedusing search programs that utilize probabilistic representations ofpolypeptide families (profiles) to search databases. For example, thePSI-BLAST program generates profiles through an iterative databasesearch process and is capable of detecting remote homologs (Atschul etal., 1997, Nucleic Acids Res. 25: 3389-3402). Even greater sensitivitycan be achieved if the family or superfamily for the polypeptide has oneor more representatives in the protein structure databases. Programssuch as GenTHREADER (Jones, 1999, J. Mol. Biol. 287: 797-815; McGuffinand Jones, 2003, Bioinformatics 19: 874-881) utilize information from avariety of sources (PSI-BLAST, secondary structure prediction,structural alignment profiles, and solvation potentials) as input to aneural network that predicts the structural fold for a query sequence.Similarly, the method of Gough et al., 2000, J. Mol. Biol. 313: 903-919,can be used to align a sequence of unknown structure with thesuperfamily models present in the SCOP database. These alignments can inturn be used to generate homology models for the polypeptide, and suchmodels can be assessed for accuracy using a variety of tools developedfor that purpose.

For proteins of known structure, several tools and resources areavailable for retrieving and generating structural alignments. Forexample the SCOP superfamilies of proteins have been structurallyaligned, and those alignments are accessible and downloadable. Two ormore protein structures can be aligned using a variety of algorithmssuch as the distance alignment matrix (Holm and Sander, 1998, Proteins33: 88-96) or combinatorial extension (Shindyalov and Bourne, 1998,Protein Engineering 11: 739-747), and implementation of these algorithmscan additionally be utilized to query structure databases with astructure of interest in order to discover possible structural homologs(e.g., Holm and Park, 2000, Bioinformatics 16: 566-567).

In describing the variants of the present invention, the nomenclaturedescribed below is adapted for ease of reference. The accepted IUPACsingle letter or three letter amino acid abbreviation is employed.

Substitutions. For an amino acid substitution, the followingnomenclature is used: Original amino acid, position, substituted aminoacid. Accordingly, the substitution of threonine at position 226 withalanine is designated as “Thr226Ala” or “T226A”. Multiple mutations areseparated by addition marks (“+”), e.g., “Gly205Arg+Ser411Phe” or“G205R+S411F”, representing substitutions at positions 205 and 411 ofglycine (G) with arginine (R) and serine (S) with phenylalanine (F),respectively.

Deletions. For an amino acid deletion, the following nomenclature isused: Original amino acid, position, *. Accordingly, the deletion ofglycine at position 195 is designated as “Gly195*” or “G195*”. Multipledeletions are separated by addition marks (“+”), e.g., “Gly195*+Ser411*”or “G195*+S411*”.

Insertions. For an amino acid insertion, the following nomenclature isused: Original amino acid, position, original amino acid, inserted aminoacid. Accordingly the insertion of lysine after glycine at position 195is designated “Gly195GlyLys” or “G195GK”. An insertion of multiple aminoacids is designated [Original amino acid, position, original amino acid,inserted amino acid #1, inserted amino acid #2; etc.]. For example, theinsertion of lysine and alanine after glycine at position 195 isindicated as “Gly195GlyLysAla” or “G195GKA”.

In such cases the inserted amino acid residue(s) are numbered by theaddition of lower case letters to the position number of the amino acidresidue preceding the inserted amino acid residue(s). In the aboveexample, the sequence would thus be:

Parent: Variant: 195 195 195a 195b G G - K - A

Multiple alterations. Variants comprising multiple alterations areseparated by addition marks (“+”), e.g., “Arg170Tyr+Gly195Glu” or“R170Y+G195E” representing a substitution of arginine and glycine atpositions 170 and 195 with tyrosine and glutamic acid, respectively.

Different alterations. Where different alterations can be introduced ata position, the different alterations are separated by a comma, e.g.,“Arg170Tyr,Glu” represents a substitution of arginine at position 170with tyrosine or glutamic acid. Thus, “Tyr167Gly,Ala +Arg170Gly,Ala”designates the following variants:

In one aspect the parent lipase is SEQ ID NO: 2, SEQ IDNO: 4, SEQ ID NO: 6, SEQ ID NO: 8, SEQ ID NO: 10, or SEQ ID NO: 12.

The amino acid changes may be of a minor nature, that is conservativeamino acid substitutions or insertions that do not significantly affectthe folding and/or activity of the protein; small deletions, typicallyof 1-30 amino acids; small amino- or carboxyl-terminal extensions, suchas an amino-terminal methionine residue; a small linker peptide of up to20-25 residues; or a small extension that facilitates purification bychanging net charge or another function, such as a poly-histidine tract,an antigenic epitope or a binding domain.

Examples of conservative substitutions are within the groups of basicamino acids (arginine, lysine and histidine), acidic amino acids(glutamic acid and aspartic acid), polar amino acids (glutamine andasparagine), hydrophobic amino acids (leucine, isoleucine and valine),aromatic amino acids (phenylalanine, tryptophan and tyrosine), and smallamino acids (glycine, alanine, serine, threonine and methionine). Aminoacid substitutions that do not generally alter specific activity areknown in the art and are described, for example, by H. Neurath and R. L.Hill, 1979, In, The Proteins, Academic Press, New York. Commonsubstitutions are Ala/Ser, Val/Ile, Asp/Glu, Thr/Ser, Ala/Gly, Ala/Thr,Ser/Asn, Ala/Val, Ser/Gly, Tyr/Phe, Ala/Pro, Lys/Arg, Asp/Asn, Leu/Ile,Leu/Val, Ala/Glu, and Asp/Gly.

Alternatively, the amino acid changes are of such a nature that thephysico-chemical properties of the polypeptides are altered. Forexample, amino acid changes may improve the thermal stability of thepolypeptide, alter the substrate specificity, change the pH optimum, andthe like.

For example, the variants may comprise a substitution at a positioncorresponding to any of positions; 1, 2, 4, 27, 33, 38, 54, 56, 57, 58,60, 69, 83, 86, 91, 94, 97, 98, 99, 101, 111, 163, 176, 210, 216, 220,225, 227, 231, 233, 249, 254, 255, 256, 263, 264, 265, 266, 267, and 269of SEQ ID NO: 2, SEQ ID NO: 4, SEQ ID NO: 6, SEQ ID NO: 8, SEQ ID NO:10, or SEQ ID NO: 12.

In some embodiments, lipase variants of the invention provide both areduced odor generation as well as an increased stability of thevariant, e.g., during storage, such as storage in a hostile environmentsuch as in a detergent composition. In this context the term “hostileenvironment”, means an environment which actively interacts negativelywith the lipase variant and reduces its lipase activity eitherreversibly or irreversibly. In this embodiment the invention provideslipase variants, wherein the variant comprises the substitution F51V andone or more substitutions selected from H198A/D/E/F/G/I/L/N/Q/S/T/V/Y,F7H/K/R, T143A/G/S/V, A150G/V, N200H/K/Q/R, I202G/L/V,S224C/F/H/I/L/P/Y, L227D/E/K/R, V228P, P229H/K/R, V230H/K/L/R,I255A/G/N/P/S/T/V/Y, P256A/K/N/Q/R/S/W or T256A/K/N/Q/R/S/P/W,A257F/H/I/L/V/Y, L259F/Y, and W260D/E/F/H/I/L/N/Q/S/T/Y, exhibiting botha reduced odor generation upon hydrolyzing a lipase substrate and animproved stability compared to the parent lipase.

Essential amino acids in a polypeptide can be identified according toprocedures known in the art, such as site-directed mutagenesis oralanine-scanning mutagenesis (Cunningham and Wells, 1989, Science 244:1081-1085). In the latter technique, single alanine mutations areintroduced at every residue in the molecule, and the resultant mutantmolecules are tested for lipase activity to identify amino acid residuesthat are critical to the activity of the molecule. See also, Hilton etal., 1996, J. Biol. Chem. 271: 4699-4708. The active site of the enzymeor other biological interaction can also be determined by physicalanalysis of structure, as determined by such techniques as nuclearmagnetic resonance, crystallography, electron diffraction, orphotoaffinity labeling, in conjunction with mutation of putative contactsite amino acids. See, e.g., de Vos et al., 1992, Science 255: 306-312;Smith et al., 1992, J. Mol. Biol. 224: 899-904; Wlodaver et al., 1992,FEBS Lett. 309: 59-64. The identity of essential amino acids can also beinferred from an alignment with a related polypeptide.

Preparation of Variants

The present invention also relates to methods for obtaining a variant ofa parent lipase having lipase activity, comprising: (a) introducing intothe parent lipase a substitution at one or more (e.g., several)positions corresponding to positions F7H/K/R, F51A/I/L/V/Y, T143A/G/S/V,A150G/V, H198A/D/E/F/G/I/L/N/Q/S/T/V/Y, N200H/K/Q/R, I202G/L/V,S224C/F/H/I/L/P/Y, L227D/E/K/R, V228P, P229H/K/R, V230H/K/L/R,I255A/G/N/P/S/T/V/Y, P256A/K/N/Q/R/S/T/W, A257F/H/I/L/V/Y, L259F/Y, andW260D/E/F/H/I/L/N/Q/S/T/Y of the parent lipase, wherein the variant haslipase activity; and (b) recovering the variant. In one aspect theparent lipase is SEQ ID NO: 2, SEQ ID NO: 4, SEQ ID NO: 6, SEQ ID NO:8,SEQ ID NO: 10, or SEQ ID NO: 12, or a fragment thereof with lipaseactivity.

The variants can be prepared using any mutagenesis procedure known inthe art, such as site-directed mutagenesis, synthetic gene construction,semi-synthetic gene construction, random mutagenesis, shuffling, etc.

Site-directed mutagenesis is a technique in which one or more (e.g.,several) mutations are introduced at one or more defined sites in apolynucleotide encoding the parent.

Site-directed mutagenesis can be accomplished in vitro by PCR involvingthe use of oligonucleotide primers containing the desired mutation.Site-directed mutagenesis can also be performed in vitro by cassettemutagenesis involving the cleavage by a restriction enzyme at a site inthe plasmid comprising a polynucleotide encoding the parent andsubsequent ligation of an oligonucleotide containing the mutation in thepolynucleotide. Usually the restriction enzyme that digests the plasmidand the oligonucleotide is the same, permitting sticky ends of theplasmid and the insert to ligate to one another. See, e.g., Scherer andDavis, 1979, Proc. Natl. Acad. Sci. USA 76: 4949-4955; and Barton etal., 1990, Nucleic Acids Res. 18: 7349-4966.

Site-directed mutagenesis can also be accomplished in vivo by methodsknown in the art. See, e.g., US 2004/0171154; Storici et al., 2001,Nature Biotechnol. 19: 773-776; Kren et al., 1998, Nat. Med. 4: 285-290;and Calissano and Macino, 1996, Fungal Genet. Newslett. 43: 15-16.

Any site-directed mutagenesis procedure can be used in the presentinvention. There are many commercial kits available that can be used toprepare variants.

Synthetic gene construction entails in vitro synthesis of a designedpolynucleotide molecule to encode a polypeptide of interest. Genesynthesis can be performed utilizing a number of techniques, such as themultiplex microchip-based technology described by Tian et al. (2004,Nature 432: 1050-1054) and similar technologies wherein oligonucleotidesare synthesized and assembled upon photo-programmable microfluidicchips.

Single or multiple amino acid substitutions, deletions, and/orinsertions can be made and tested using known methods of mutagenesis,recombination, and/or shuffling, followed by a relevant screeningprocedure, such as those disclosed by Reidhaar-Olson and Sauer, 1988,Science 241: 53-57; Bowie and Sauer, 1989, Proc. Natl. Acad. Sci. USA86: 2152-2156; WO 95/17413; or WO 95/22625. Other methods that can beused include error-prone PCR, phage display (e.g., Lowman et al., 1991,Biochemistry 30: 10832-10837; U.S. Pat. No. 5,223,409; WO 92/06204) andregion-directed mutagenesis (Derbyshire et al., 1986, Gene 46: 145; Neret al., 1988, DNA 7: 127).

Mutagenesis/shuffling methods can be combined with high-throughput,automated screening methods to detect activity of cloned, mutagenizedpolypeptides expressed by host cells (Ness et al., 1999, NatureBiotechnology 17: 893-896). Mutagenized DNA molecules that encode activepolypeptides can be recovered from the host cells and rapidly sequencedusing standard methods in the art. These methods allow the rapiddetermination of the importance of individual amino acid residues in apolypeptide.

Semi-synthetic gene construction is accomplished by combining aspects ofsynthetic gene construction, and/or site-directed mutagenesis, and/orrandom mutagenesis, and/or shuffling. Semi-synthetic construction istypified by a process utilizing polynucleotide fragments that aresynthesized, in combination with PCR techniques. Defined regions ofgenes may thus be synthesized de novo, while other regions may beamplified using site-specific mutagenic primers, while yet other regionsmay be subjected to error-prone PCR or non-error prone PCRamplification. Polynucleotide subsequences may then be shuffled.

Suitable leaders for yeast host cells are obtained from the genes forSaccharomyces cerevisiae enolase (ENO-1), Saccharomyces cerevisiae3-phosphoglycerate kinase, Saccharomyces cerevisiae alpha-factor, andSaccharomyces cerevisiae alcoholdehydrogenase/glyceraldehyde-3-phosphate dehydrogenase (ADH2/GAP).

The control sequence may also be a polyadenylation sequence, a sequenceoperably linked to the 3′-terminus of the variant-encoding sequence and,when transcribed, is recognized by the host cell as a signal to addpolyadenosine residues to transcribed mRNA. Any polyadenylation sequencethat is functional in the host cell may be used.

Preferred polyadenylation sequences for filamentous fungal host cellsare obtained from the genes for Aspergillus nidulans anthranilatesynthase, Aspergillus niger glucoamylase, Aspergillus nigeralpha-glucosidase, Aspergillus oryzae TAKA amylase, and Fusariumoxysporum trypsin-like protease.

Useful polyadenylation sequences for yeast host cells are described byGuo and Sherman, 1995, Mol. Cellular Biol. 15: 5983-5990.

The control sequence may also be a signal peptide coding region thatencodes a signal peptide linked to the N-terminus of a variant anddirects the variant into the cell's secretory pathway. The 5′-end of thecoding sequence of the polynucleotide may inherently contain a signalpeptide coding sequence naturally linked in translation reading framewith the segment of the coding sequence that encodes the variant.Alternatively, the 5′-end of the coding sequence may contain a signalpeptide coding sequence that is foreign to the coding sequence. Aforeign signal peptide coding sequence may be required where the codingsequence does not naturally contain a signal peptide coding sequence.Alternatively, a foreign signal peptide coding sequence may simplyreplace the natural signal peptide coding sequence in order to enhancesecretion of the variant. However, any signal peptide coding sequencethat directs the expressed variant into the secretory pathway of a hostcell may be used.

Effective signal peptide coding sequences for bacterial host cells arethe signal peptide coding sequences obtained from the genes for BacillusNCIB 11837 maltogenic amylase, Bacillus licheniformis subtilisin,Bacillus licheniformis beta-lactamase, Bacillus stearothermophilusalpha-amylase, Bacillus stearothermophilus neutral proteases (nprT,nprS, nprM), and Bacillus subtilis prsA. Further signal peptides aredescribed by Simonen and Palva, 1993, Microbiological Reviews 57:109-137.

Effective signal peptide coding sequences for filamentous fungal hostcells are the signal peptide coding sequences obtained from the genesfor Aspergillus niger neutral amylase, Aspergillus niger glucoamylase,Aspergillus oryzae TAKA amylase, Humicola insolens cellulase, Humicolainsolens endoglucanase V, Humicola lanuginosa lipase, and Rhizomucormiehei aspartic proteinase.

Useful signal peptides for yeast host cells are obtained from the genesfor Saccharomyces cerevisiae alpha-factor and Saccharomyces cerevisiaeinvertase. Other useful signal peptide coding sequences are described byRomanos et al., 1992, supra.

The control sequence may also be a propeptide coding sequence thatencodes a propeptide positioned at the N-terminus of a variant. Theresultant polypeptide is known as a proenzyme or propolypeptide (or azymogen in some cases). A propolypeptide is generally inactive and canbe converted to an active polypeptide by catalytic or autocatalyticcleavage of the propeptide from the propolypeptide. The propeptidecoding sequence may be obtained from the genes for Bacillus subtilisalkaline protease (aprE), Bacillus subtilis neutral protease (nprT),Myceliophthora thermophila laccase (WO 95/33836), Rhizomucor mieheiaspartic proteinase, and Saccharomyces cerevisiae alpha-factor.

Where both signal peptide and propeptide sequences are present, thepropeptide sequence is positioned next to the N-terminus of the variantand the signal peptide sequence is positioned next to the N-terminus ofthe propeptide sequence.

It may also be desirable to add regulatory sequences that regulateexpression of the variant relative to the growth of the host cell.Examples of regulatory systems are those that cause expression of thegene to be turned on or off in response to a chemical or physicalstimulus, including the presence of a regulatory compound. Regulatorysystems in prokaryotic systems include the lac, tac, and trp operatorsystems. In yeast, the ADH2 system or GAL1 system may be used. Infilamentous fungi, the Aspergillus niger glucoamylase promoter,Aspergillus oryzae TAKA alpha-amylase promoter, and Aspergillus oryzaeglucoamylase promoter may be used. Other examples of regulatorysequences are those that allow for gene amplification. In eukaryoticsystems, these regulatory sequences include the dihydrofolate reductasegene that is amplified in the presence of methotrexate, and themetallothionein genes that are amplified with heavy metals. In thesecases, the polynucleotide encoding the variant would be operably linkedwith the regulatory sequence.

Expression Vectors

The present invention also relates to recombinant expression vectorscomprising a polynucleotide encoding a variant of the present invention,a promoter, and transcriptional and translational stop signals. Thevarious nucleotide and control sequences may be joined together toproduce a recombinant expression vector that may include one or moreconvenient restriction sites to allow for insertion or substitution ofthe polynucleotide encoding the variant at such sites. Alternatively,the polynucleotide may be expressed by inserting the polynucleotide or anucleic acid construct comprising the polynucleotide into an appropriatevector for expression. In creating the expression vector, the codingsequence is located in the vector so that the coding sequence isoperably linked with the appropriate control sequences for expression.

The recombinant expression vector may be any vector (e.g., a plasmid orvirus) that can be conveniently subjected to recombinant DNA proceduresand can bring about expression of the polynucleotide. The choice of thevector will typically depend on the compatibility of the vector with thehost cell into which the vector is to be introduced. The vector may be alinear or closed circular plasmid.

The vector may be an autonomously replicating vector, i.e., a vectorthat exists as an extrachromosomal entity, the replication of which isindependent of chromosomal replication, e.g., a plasmid, anextrachromosomal element, a minichromosome, or an artificial chromosome.The vector may contain any means for assuring self-replication.Alternatively, the vector may be one that, when introduced into the hostcell, is integrated into the genome and replicated together with thechromosome(s) into which it has been integrated. Furthermore, a singlevector or plasmid or two or more vectors or plasmids that togethercontain the total DNA to be introduced into the genome of the host cell,or a transposon, may be used.

The vector preferably contains one or more selectable markers thatpermit easy selection of transformed, transfected, transduced, or thelike cells. A selectable marker is a gene the product of which providesfor biocide or viral resistance, resistance to heavy metals, prototrophyto auxotrophs, and the like.

Examples of bacterial selectable markers are Bacillus licheniformis orBacillus subtilis dal genes, or markers that confer antibioticresistance such as ampicillin, chloramphenicol, kanamycin, neomycin,spectinomycin or tetracycline resistance. Suitable markers for yeasthost cells include, but are not limited to, ADE2, HIS3, LEU2, LYS2,MET3, TRP1, and URA3. Selectable markers for use in a filamentous fungalhost cell include, but are not limited to, amdS (acetamidase), argB(ornithine carbamoyltransferase), bar (phosphinothricinacetyltransferase), hph (hygromycin phosphotransferase), niaD (nitratereductase), pyrG (orotidine-5′-phosphate decarboxylase), sC (sulfateadenyltransferase), and trpC (anthranilate synthase), as well asequivalents thereof. Preferred for use in an Aspergillus cell areAspergillus nidulans or Aspergillus oryzae amdS and pyrG genes and aStreptomyces hygroscopicus bar gene.

The vector preferably contains an element(s) that permits integration ofthe vector into the host cell's genome or autonomous replication of thevector in the cell independent of the genome.

For integration into the host cell genome, the vector may rely on thepolynucleotide's sequence encoding the variant or any other element ofthe vector for integration into the genome by homologous ornon-homologous recombination. Alternatively, the vector may containadditional polynucleotides for directing integration by homologousrecombination into the genome of the host cell at a precise location(s)in the chromosome(s). To increase the likelihood of integration at aprecise location, the integrational elements should contain a sufficientnumber of nucleic acids, such as 100 to 10,000 base pairs, 400 to 10,000base pairs, and 800 to 10,000 base pairs, which have a high degree ofsequence identity to the corresponding target sequence to enhance theprobability of homologous recombination. The integrational elements maybe any sequence that is homologous with the target sequence in thegenome of the host cell. Furthermore, the integrational elements may benon-encoding or encoding polynucleotides. On the other hand, the vectormay be integrated into the genome of the host cell by non-homologousrecombination.

For autonomous replication, the vector may further comprise an origin ofreplication enabling the vector to replicate autonomously in the hostcell in question. The origin of replication may be any plasmidreplicator mediating autonomous replication that functions in a cell.The term “origin of replication” or “plasmid replicator” means apolynucleotide that enables a plasmid or vector to replicate in vivo.

Examples of bacterial origins of replication are the origins ofreplication of plasmids pBR322, pUC19, pACYC177, and pACYC184 permittingreplication in E. coli, and pUB110, pE194, pTA1060, and pAMß1 permittingreplication in Bacillus.

Examples of origins of replication for use in a yeast host cell are the2 micron origin of replication, ARS1, ARS4, the combination of ARS1 andCEN3, and the combination of ARS4 and CEN6.

Examples of origins of replication useful in a filamentous fungal cellare AMA1 and ANS1 (Gems et al., 1991, Gene 98: 61-67; Cullen et al.,1987, Nucleic Acids Res. 15: 9163-9175; WO 00/24883). Isolation of theAMA1 gene and construction of plasmids or vectors comprising the genecan be accomplished according to the methods disclosed in WO 00/24883.

More than one copy of a polynucleotide of the present invention may beinserted into a host cell to increase production of a variant. Anincrease in the copy number of the polynucleotide can be obtained byintegrating at least one additional copy of the sequence into the hostcell genome or by including an amplifiable selectable marker gene withthe polynucleotide where cells containing amplified copies of theselectable marker gene, and thereby additional copies of thepolynucleotide, can be selected for by cultivating the cells in thepresence of the appropriate selectable agent.

The procedures used to ligate the elements described above to constructthe recombinant expression vectors of the present invention are wellknown to one skilled in the art (see, e.g., Sambrook et al., 1989,supra).

Host Cells

The present invention also relates to recombinant host cells, comprisinga polynucleotide encoding a variant of the present invention operablylinked to one or more control sequences that direct the production of avariant of the present invention. A construct or vector comprising apolynucleotide is introduced into a host cell so that the construct orvector is maintained as a chromosomal integrant or as a self-replicatingextra-chromosomal vector as described earlier. The term “host cell”encompasses any progeny of a parent cell that is not identical to theparent cell due to mutations that occur during replication. The choiceof a host cell will to a large extent depend upon the gene encoding thevariant and its source.

The host cell may be any cell useful in the recombinant production of avariant, e.g., a prokaryote or a eukaryote.

The prokaryotic host cell may be any Gram-positive or Gram-negativebacterium. Gram-positive bacteria include, but are not limited to,Bacillus, Clostridium, Enterococcus, Geobacillus, Lactobacillus,Lactococcus, Oceanobacillus, Staphylococcus, Streptococcus, andStreptomyces.

Gen.Genet. 168: 111-115), competent cell transformation (see, e.g., Youngand Spizizen, 1961, J. Bacteriol. 81: 823-829, or Dubnau andDavidoff-Abelson, 1971, J. Mol. Biol. 56: 209-221), electroporation(see, e.g., Shigekawa and Dower, 1988, Biotechniques 6: 742-751), orconjugation (see, e.g., Koehler and Thorne, 1987, J. Bacteriol. 169:5271-5278). The introduction of DNA into an E. coli cell may be effectedby protoplast transformation (see, e.g., Hanahan, 1983, J. Mol. Biol.166: 557-580) or electroporation (see, e.g., Dower et al., 1988, NucleicAcids Res. 16: 6127-6145). The introduction of DNA into a Streptomycescell may be effected by protoplast transformation, electroporation (see,e.g., Gong et al., 2004, Folia Microbiol. (Praha) 49: 399-405),conjugation (see, e.g., Mazodier et al., 1989, J. Bacteriol. 171:3583-3585), or transduction (see, e.g., Burke et al., 2001, Proc. Natl.Acad. Sci. USA 98: 6289-6294). The introduction of DNA into aPseudomonas cell may be effected by electroporation (see, e.g., Choi etal., 2006, J. Microbiol. Methods 64: 391-397), or conjugation (see,e.g., Pinedo and Smets, 2005, Appl. Environ. Microbiol. 71: 51-57). Theintroduction of DNA into a Streptococcus cell may be effected by naturalcompetence (see, e.g., Perry and Kuramitsu, 1981, Infect. Immun. 32:1295-1297), protoplast transformation (see, e.g., Catt and Jollick,1991, Microbios 68: 189-207), electroporation (see, e.g., Buckley etal., 1999, Appl. Environ.

Soap—The compositions herein may contain soap. Without being limited bytheory, it may be desirable to include soap as it acts in part as asurfactant and in part as a builder and may be useful for suppression offoam and may furthermore interact favorably with the various cationiccompounds of the composition to enhance softness on textile fabricstreaded with the inventive compositions. Any soap known in the art foruse in laundry detergents may be utilized. In one aspect, thecompositions contain from 0 to 20 wt. %, from 0.5 to 20 wt. %, from 4 to10 wt. %, or from 4 to 7 wt. % of soap.

Hydrotropes—The compositions of the present invention may comprise oneor more hydrotropes. A hydrotrope is a compound that solubiliseshydrophobic compounds in aqueous solutions (or oppositely, polarsubstances in a non-polar environment). Typically, hydrotropes have bothhydrophilic and a hydrophobic character (so-called amphiphilicproperties as known from surfactants); however the molecular structureof hydrotropes generally do not favor spontaneous self-aggregation, see,e.g., review by Hodgdon and Kaler, 2007, Current Opinion in Colloid &Interface Science 12: 121-128. Hydrotropes do not display a criticalconcentration above which self-aggregation occurs as found forsurfactants and lipids forming miceller, lamellar or other well definedmeso-phases. Instead, many hydrotropes show a continuous-typeaggregation process where the sizes of aggregates grow as concentrationincreases. However, many hydrotropes alter the phase behavior,stability, and colloidal properties of systems containing substances ofpolar and non-polar character, including mixtures of water, oil,surfactants, and polymers. Hydrotropes are classically used acrossindustries from pharma, personal care, food, to technical applications.Use of hydrotropes in detergent compositions allow for example moreconcentrated formulations of surfactants (as in the process ofcompacting liquid detergents by removing water) without inducingundesired phenomena such as phase separation or high viscosity.

The detergent may contain from 0 to 10 wt. %, such as from 0 to 5 wt. %,0.5 to 5 wt. %, or from 3 to 5 wt. %, of a hydrotrope. Any hydrotropeknown in the art for use in detergents may be utilized.

Typically the particle size, measured asequivalent spherical diameter (volume based average particle size), ofthe lipase particles is below 2 mm, preferably below 1 mm, below 0.5 mm,below 0.25 mm, or below 0.1 mm; and above 0.05 um, preferably above 0.1um, above 0.5 um, above 1 um, above 5 um or above 10 um. In a preferredembodiment, the particle size of the lipase particles is from 0.5 um to100 um.

The lipase particles contain at least 1% w/w lipase protein, preferablyat least 5% w/w lipase protein, at least 10% w/w lipase protein, atleast 20% w/w lipase protein, at least 30% w/w lipase protein, at least40% w/w lipase protein, at least 50% w/w lipase protein, at least 60%w/w lipase protein, at least 70% w/w lipase protein, at least 80% w/wlipase protein, or at least 90%w/w lipase protein.

In a preferred embodiment, the lipase particles are lipase crystals, orthe lipase protein is on a crystalline form. Enzyme crystallization maybe carried out in a number of ways, as known in the art (e.g., asdescribed in WO 91/09943 or WO 94/22903).

The lipase may be formulated in the lipase particle as known in the artfor solid enzyme formulations, such as formulations for reducing dust,improving stability and/or modifying relase rate of the enzyme. Thelipase particle may also be formulated in a matrix or coated with agentssuppressing dissolution of the enzyme particle in the PVOH/film solutionused for preparing the water-soluble film.

The lipase molecules on the surface of the lipase particles may also becross-linked, like CLECs (Cross-Linked Enzyme Crystals) or CLEA(Cross-Linked Enzyme Aggregate).

Water-Soluble Film

Water-soluble films, optional ingredients for use therein, and methodsof making the same are well known in the art. In one class ofembodiments, the water-soluble film includes PVOH. PVOH is a syntheticresin generally prepared by the alcoholysis, usually termed hydrolysisor saponification, of polyvinyl acetate. Fully hydrolyzed PVOH, whereinvirtually all the acetate groups have been converted to alcohol groups,is a strongly hydrogen-bonded, highly crystalline polymer whichdissolves only in hot water—greater than about 140° F. (60° C.). If asufficient number of acetate groups are allowed to remain after thehydrolysis of polyvinyl acetate, the PVOH polymer then being known aspartially hydrolyzed, it is more weakly hydrogen-bonded and lesscrystalline and is soluble in cold water—less than about 50° F. (10°C.). An intermediate cold/hot water-soluble film can include, forexample, intermediate partially-hydrolyzed PVOH (e.g., with degrees ofhydrolysis of about 94% to about 98%), and is readily soluble only inwarm water—e.g., rapid dissolution at temperatures of about 40° C. andgreater. Both fully and partially hydrolyzed PVOH types are commonlyreferred to as PVOH homopolymers although the partially hydrolyzed typeis technically a vinyl alcohol-vinyl acetate copolymer.

The degree of hydrolysis of the PVOH included in the water-soluble filmsmay be about 75% to about 99%. As the degree of hydrolysis is reduced, afilm made from the resin will have reduced mechanical strength butfaster solubility at temperatures below about 20° C. As the degree ofhydrolysis increases, a film made from the resin will tend to bemechanically stronger and the thermoformability will tend to decrease.The degree of hydrolysis of the PVOH can be chosen such that thewater-solubility of the resin is temperature dependent, and thus thesolubility of a film made from the resin, compatibilizing agent, andadditional ingredients is also influenced. In one class of embodimentsthe film is cold water-soluble. A cold water-soluble film, soluble inwater at a temperature of less than 10° C., can include PVOH with adegree of hydrolysis in a range of about 75% to about 90%, or in a rangeof about 80% to about 90%, or in a range of about 85% to about 90%. Inanother class of embodiments the film is hot water-soluble. A hotwater-soluble film, soluble in water at a temperature of at least about60° C., can include PVOH with a degree of hydrolysis of at least about98%.

Other film-forming resins for use in addition to or in an alternative toPVOH can include, but are not limited to, modified polyvinyl alcohols,polyacrylates, water-soluble acrylate copolymers, polyacrylates,polyacryamides, polyvinyl pyrrolidone, pullulan, water-soluble naturalpolymers including, but not limited to, guar gum, xanthan gum,carrageenan, and starch, water-soluble polymer derivatives including,but not limited to, ethoxylated starch and hydroxypropylated starch,poly(sodium acrylamido-2-methylpropane sulfonate),polymonomethylmaleate, copolymers thereof, and combinations of any ofthe foregoing. In one class of embodiments, the film-forming resin is aterpolymer consisting of vinyl alcohol, vinyl acetate, and sodiumacrylamido-2-methylpropanesulfonate. Unexpectedly, water-soluble filmsbased on a vinyl alcohol, vinyl acetate, and sodiumacrylamido-2-methylpropanesulfonate terpolymer have demonstrated a highpercent recovery of enzyme.

The water-soluble resin can be included in the water-soluble film in anysuitable amount, for example an amount in a range of about 35 wt. % toabout 90 wt. %. The preferred weight ratio of the amount of thewater-soluble resin as compared to the combined amount of all enzymes,enzyme stabilizers, and secondary additives can be any suitable ratio,for example a ratio in a range of about 0.5 to about 5, or about 1 to 3,or about 1 to 2.

Water-soluble resins for use in the films described herein (including,but not limited to PVOH resins) can be characterized by any suitableviscosity for the desired film properties, optionally a viscosity in arange of about 5.0 to about 30.0 cP, or about 10.0 cP to about 25 cP.The viscosity of a PVOH resin is determined by measuring a freshly madesolution using a Brookfield LV type viscometer with UL adapter asdescribed in British Standard EN ISO 15023-2:2006 Annex E BrookfieldTest method. It is international practice to state the viscosity of 4%aqueous polyvinyl alcohol solutions at 20° C. All PVOH viscositiesspecified herein in cP should be understood to refer to the viscosity of4% aqueous polyvinyl alcohol solution at 20° C., unless specifiedotherwise.

It is well known in the art that the viscosity of a PVOH resin iscorrelated with the weight average molecular weight of the same PVOHresin, and often the viscosity is used as a proxy for the weight averagemolecular weight. Thus, the weight average molecular weight of thewater-soluble resin optionally can be in a range of about 35,000 toabout 190,000, or about 80,000 to about 160,000. The molecular weight ofthe resin need only be sufficient to enable it to be molded by suitabletechniques to form a thin plastic film.

The water-soluble films may include other optional additive ingredientsincluding, but not limited to, plasticizers, surfactants, defoamers,film formers, antiblocking agents, internal release agents,anti-yellowing agents and other functional ingredients, for example inamounts suitable for their intended purpose.

Water is recognized as a very efficient plasticizer for PVOH and otherpolymers; however, the volatility of water makes its utility limitedsince polymer films need to have at least some resistance (robustness)to a variety of ambient conditions including low and high relativehumidity. Glycerin is much less volatile than water and has been wellestablished as an effective plasticizer for PVOH and other polymers.Glycerin or other such liquid plasticizers by themselves can causesurface “sweating” and greasiness if the level used in the filmformulation is too high. This can lead to problems in a film such asunacceptable feel to the hand of the consumer and even blocking of thefilm on the roll or in stacks of sheets if the sweating is not mitigatedin some manner, such as powdering of the surface. This could becharacterized as over plasticization. However, if too little plasticizeris added to the film the film may lack sufficient ductility andflexibility for many end uses, for example to be converted into a finaluse format such as pouches.

Plasticizers for use in water-soluble films of the present disclosureinclude, but are not limited to, sorbitol, glycerol, diglycerol,propylene glycol, ethylene glycol, diethyleneglycol, triethylene glycol,tetraethyleneglycol, polyethylene glycols up to MW 400, 2 methyl 1,3propane diol, lactic acid, monoacetin, triacetin, triethyl citrate,1,3-butanediol, trimethylolpropane (TMP), polyether triol, andcombinations thereof. Polyols, as described above, are generally usefulas plasticizers. As less plasticizer is used, the film can become morebrittle, whereas as more plasticizer is used the film can lose tensilestrength. Plasticizers can be included in the water-soluble films in anamount in a range of about 25 phr to about 50 phr, or from about 30 phrto about 45 phr, or from about 32 phr to about 42 phr, for example.

Surfactants for use in water-soluble films are well known in the art.Optionally, surfactants are included to aid in the dispersion of theresin solution upon casting. Suitable surfactants for water-solublefilms of the present disclosure include, but are not limited to, dialkylsulfosuccinates, lactylated fatty acid esters of glycerol and propyleneglycol, lactylic esters of fatty acids, sodium alkyl sulfates,polysorbate 20, polysorbate 60, polysorbate 65, polysorbate 80, alkylpolyethylene glycol ethers, lecithin, acetylated fatty acid esters ofglycerol and propylene glycol, sodium lauryl sulfate, acetylated estersof fatty acids, myristyl dimethylamine oxide, trimethyl tallow alkylammonium chloride, quaternary ammonium compounds, salts thereof andcombinations of any of the forgoing. Thus, surfactants can be includedin the water-soluble films in an amount of less than about 2 phr, forexample less than about 1 phr, or less than about 0.5 phr, for example.

One type of secondary component contemplated for use is a defoamer.Defoamers can aid in coalescing of foam bubbles. Suitable defoamers foruse in water-soluble films according to the present disclosure include,but are not limited to, hydrophobic silicas, for example silicon dioxideor fumed silica in fine particle sizes, including Foam Blast® defoamersavailable from Emerald Performance Materials, including Foam Blast® 327,Foam Blast® UVD, Foam Blast® 163, Foam Blast® 269, Foam Blast® 338, FoamBlast® 290, Foam Blast® 332, Foam Blast® 349, Foam Blast® 550 and FoamBlast® 339, which are proprietary, non-mineral oil defoamers. Inembodiments, defoamers can be used in an amount of 0.5 phr, or less, forexample, 0.05 phr, 0.04 phr, 0.03 phr, 0.02 phr, or 0.01 phr.Preferably, significant amounts of silicon dioxide will be avoided, inorder to avoid stress whitening.

Processes for making water-soluble articles, including films, includecasting, blow-molding, extrusion and blown extrusion, as known in theart. One contemplated class of embodiments is characterized by thewater-soluble film described herein being formed by casting, forexample, by admixing the ingredients described herein with water tocreate an aqueous mixture, for example a solution with optionallydispersed solids, applying the mixture to a surface, and drying offwater to create a film. Similarly, other compositions can be formed bydrying the mixture while it is confined in a desired shape.

In one contemplated class of embodiments, the water-soluble film isformed by casting a water-soluble mixture wherein the water-solublemixture is prepared according to the steps of:

-   -   (a) providing a mixture of water-soluble resin, water, and any        optional additives excluding plasticizers;    -   (b) boiling the mixture for 30 minutes;    -   (c) degassing the mixture in an oven at a temperature of at        least 40° C.; optionally in a range of 40° C. to 70° C., e.g.,        about 65° C.;    -   (d) adding one or more enzymes, plasticizer, and additional        water to the mixture at a temperature of 65° C. or less;    -   (e) stirring the mixture without vortex until the mixture        appears substantially uniform in color and consistency;        optionally for a time period in a range of 30 minutes to 90        minutes, optionally at least 1 hour; and    -   (f) casting the mixture promptly after the time period of        stirring (e.g., within 4 hours, or 2 hours, or 1 hour).

If the enzyme is added to the mixture too early, e.g., with thesecondary additives or resin, the activity of the enzyme may decrease.Without intending to be bound by any particular theory, it is believedthat boiling of the mixture with the enzyme leads to the enzymedenaturing and storing in solution for extended periods of time alsoleads to a reduction in enzyme activity.

In one class of embodiments, high enzyme activity is maintained in thewater-soluble films according to the present disclosure by drying thefilms quickly under moderate to mild conditions. As used herein, dryingquickly refers to a drying time of less than 24 hours, optionally lessthan 12 hours, optionally less than 8 hours, optionally less than 2hours, optionally less than 1 hour, optionally less than 45 minutes,optionally less than 30 minutes, optionally less than 20 minutes,optionally less than 10 minutes, for example in a range of about 6minutes to about 10 minutes, or 8 minutes. As used herein, moderate tomild conditions refer to drying temperatures of less than 170° F. (77°C.), optionally in a range of about 150° F. to about 170° F. (about 66°C. to about 77° C.), e.g., 165° F. (74° C.). As the drying temperatureincreases, the enzymes tend to denature faster, whereas as the dryingtemperature decreases, the drying time increases, thus exposing theenzymes to solution for an extended period of time.

The film is useful for creating a packet to contain a composition, forexample laundry or dishwashing compositions, thereby forming a pouch.The film described herein can also be used to make a packet with two ormore compartments made of the same film or in combination with films ofother polymeric materials. Additional films can, for example, beobtained by casting, blow-molding, extrusion or blown extrusion of thesame or a different polymeric material, as known in the art. In one typeof embodiment, the polymers, copolymers or derivatives thereof suitablefor use as the additional film are selected from polyvinyl alcohols,polyvinyl pyrrolidone, polyalkylene oxides, polyacrylic acid, cellulose,cellulose ethers, cellulose esters, cellulose amides, polyvinylacetates, polycarboxylic acids and salts, polyaminoacids or peptides,polyamides, polyacrylamide, copolymers of maleic/acrylic acids,polysaccharides including starch and gelatin, natural gums such asxanthan, and carrageenans. For example, polymers can be selected frompolyacrylates and water-soluble acrylate copolymers, methylcellulose,carboxymethylcellulose sodium, dextrin, ethylcellulose, hydroxyethylcellulose, hydroxypropyl methylcellulose, maltodextrin,polymethacrylates, and combinations thereof, or selected from polyvinylalcohols, polyvinyl alcohol copolymers and hydroxypropyl methylcellulose (HPMC), and combinations thereof.

The pouches and/or packets may comprise at least one sealed compartment.Thus the pouches may comprise a single compartment or multiplecompartments. The pouches may have regions with and without enzymes. Inembodiments including multiple compartments, each compartment maycontain identical and/or different compositions. In turn, thecompositions may take any suitable form including, but not limited toliquid, solid and combinations thereof (e.g., a solid suspended in aliquid). In some embodiments, the pouches comprises a first, second andthird compartment, each of which respectively contains a differentfirst, second and third composition. In some embodiments, thecompositions may be visually distinct as described in EP 2258820.

The compartments of multi-compartment pouches and/or packets may be ofthe same or different size(s) and/or volume(s). The compartments of thepresent multi-compartment pouches can be separate or conjoined in anysuitable manner. In some embodiments, the second and/or third and/orsubsequent compartments are superimposed on the first compartment. Inone aspect, the third compartment may be superimposed on the secondcompartment, which is in turn superimposed on the first compartment in asandwich configuration. Alternatively the second and third compartmentsmay be superimposed on the first compartment. However it is also equallyenvisaged that the first, second and optionally third and subsequentcompartments may be attached to one another in a side by siderelationship. The compartments may be packed in a string, eachcompartment being individually separable by a perforation line. Henceeach compartment may be individually torn-off from the remainder of thestring by the end-user.

In some embodiments, multi-compartment pouches and/or packets includethree compartments consisting of a large first compartment and twosmaller compartments. The second and third smaller compartments aresuperimposed on the first larger compartment. The size and geometry ofthe compartments are chosen such that this arrangement is achievable.The geometry of the compartments may be the same or different. In someembodiments the second and optionally third compartment each has adifferent geometry and shape as compared to the first compartment. Inthese embodiments, the second and optionally third compartments arearranged in a design on the first compartment. The design may bedecorative, educative, or illustrative, for example to illustrate aconcept or instruction, and/or used to indicate origin of the product.In some embodiments, the first compartment is the largest compartmenthaving two large faces sealed around the perimeter, and the secondcompartment is smaller covering less than about 75%, or less than about50% of the surface area of one face of the first compartment. Inembodiments in which there is a third compartment, the aforementionedstructure may be the same but the second and third compartments coverless than about 60%, or less than about 50%, or less than about 45% ofthe surface area of one face of the first compartment.

The pouches and/or packets may comprise one or more different films. Forexample, in single compartment embodiments, the packet may be made fromone wall that is folded onto itself and sealed at the edges, oralternatively, two walls that are sealed together at the edges. Inmultiple compartment embodiments, the packet may be made from one ormore films such that any given packet compartment may comprise wallsmade from a single film or multiple films having differing compositions.In one aspect, a multi-compartment pouch comprises at least three walls:an outer upper wall; an outer lower wall; and a partitioning wall. Theouter upper wall and the outer lower wall are generally opposing andform the exterior of the pouch. The partitioning wall is interior to thepouch and is secured to the generally opposing outer walls along a sealline.

The partitioning wall separates the interior of the multi-compartmentpouch into at least a first compartment and a second compartment. In oneclass of embodiments, the partitioning wall may be the only enzymecontaining film thereby minimizing the exposure of the consumer to theenzymes.

Pouches and packets may be made using any suitable equipment and method.For example, single compartment pouches may be made using vertical formfilling, horizontal form filling, or rotary drum filling techniquescommonly known in the art. Such processes may be either continuous orintermittent. The film may be dampened, and/or heated to increase themalleability thereof. The method may also involve the use of a vacuum todraw the film into a suitable mold. The vacuum drawing the film into themold can be applied for about 0.2 to about 5 seconds, or about 0.3 toabout 3, or about 0.5 to about 1.5 seconds, once the film is on thehorizontal portion of the surface. This vacuum can be such that itprovides an under-pressure in a range of 10 mbar to 1000 mbar, or in arange of 100 mbar to 600 mbar, for example.

The molds, in which packets may be made, can have any shape, length,width and depth, depending on the required dimensions of the pouches.The molds may also vary in size and shape from one to another, ifdesirable. For example, the volume of the final pouches may be about 5mL to about 300 mL, or about 10 mL to 150 mL, or about 20 mL to about100 mL, and that the mold sizes are adjusted accordingly.

In one aspect, the packet includes a first and a second sealedcompartment. The second compartment is in a generally superposedrelationship with the first sealed compartment such that the secondsealed compartment and the first sealed compartment share a partitioningwall interior to the pouch.

In one aspect, the packet including a first and a second compartmentfurther includes a third sealed compartment. The third sealedcompartment is in a generally superposed relationship with the firstsealed compartment such that the third sealed compartment and the firstsealed compartment share a partitioning wall interior to the pouch.

In various aspects, the first composition and the second composition areselected from one of the following combinations: liquid, liquid; liquid,powder; powder, powder; and powder, liquid.

In various aspects, the first, second and third compositions areselected from one of the following combinations: solid, liquid, liquidand liquid, liquid, liquid.

In one aspect, the single compartment or plurality of sealedcompartments contains a composition. The plurality of compartments mayeach contain the same or a different composition. The composition isselected from a liquid, solid or combination thereof.

Heat can be applied to the film in the process commonly known asthermoforming. The heat may be applied using any suitable means. Forexample, the film may be heated directly by passing it under a heatingelement or through hot air, prior to feeding it onto a surface or onceon a surface. Alternatively, it may be heated indirectly, for example byheating the surface or applying a hot item onto the film. The film canbe heated using an infrared light. The film may be heated to atemperature of at least 50° C., for example about 50 to about 150° C.,about 50 to about 120° C., about 60 to about 130° C., about 70 to about120° C., or about 60 to about 90° C.

Alternatively, the film can be wetted by any suitable means, for exampledirectly by spraying a wetting agent (including water, a solution of thefilm composition, a plasticizer for the film composition, or anycombination of the foregoing) onto the film, prior to feeding it ontothe surface or once on the surface, or indirectly by wetting the surfaceor by applying a wet item onto the film.

Once a film has been heated and/or wetted, it may be drawn into anappropriate mold, preferably using a vacuum. The film can bethermoformed with a draw ratio of at least about 1.5, for example, andoptionally up to a draw ratio of 2, for example. The filling of themolded film can be accomplished by utilizing any suitable means. In someembodiments, the most preferred method will depend on the product formand required speed of filling. In some embodiments, the molded film isfilled by in-line filling techniques. The filled, open packets are thenclosed forming the pouches, using a second film, by any suitable method.This may be accomplished while in horizontal position and in continuous,constant motion. The closing may be accomplished by continuously feedinga second film, preferably water-soluble film, over and onto the openpackets and then preferably sealing the first and second film together,typically in the area between the molds and thus between the packets.

Any suitable method of sealing the packet and/or the individualcompartments thereof may be utilized. Non-limiting examples of suchmeans include heat sealing, solvent welding, solvent or wet sealing, andcombinations thereof. The water-soluble packet and/or the individualcompartments thereof can be heat sealed at a temperature of at least200° F. (93° C.), for example in a range of about 220° F. (about 105°C.) to about 290° F. (about 145° C.), or about 230° F. (about 110° C.)to about 280° F. (about 140° C.). Typically, only the area which is toform the seal is treated with heat or solvent. The heat or solvent canbe applied by any method, typically on the closing material, andtypically only on the areas which are to form the seal. If solvent orwet sealing or welding is used, it may be preferred that heat is alsoapplied. Preferred wet or solvent sealing/welding methods includeselectively applying solvent onto the area between the molds, or on theclosing material, by for example, spraying or printing this onto theseareas, and then applying pressure onto these areas, to form the seal.Sealing rolls and belts as described above (optionally also providingheat) can be used, for example.

The formed pouches may then be cut by a cutting device. Cutting can beaccomplished using any known method. It may be preferred that thecutting is also done in continuous manner, and preferably with constantspeed and preferably while in horizontal position. The cutting devicecan, for example, be a sharp item, or a hot item, or a laser, whereby inthe latter cases, the hot item or laser ‘burns’ through the film/sealingarea.

The different compartments of a multi-compartment pouches may be madetogether in a side-by-side style wherein the resulting, cojoined pouchesmay or may not be separated by cutting. Alternatively, the compartmentscan be made separately.

In some embodiments, pouches may be made according to a processincluding the steps of:

-   -   a) forming a first compartment (as described above);    -   b) forming a recess within some or all of the closed compartment        formed in step (a), to generate a second molded compartment        superposed above the first compartment;    -   c) filling and closing the second compartments by means of a        third film;    -   d) sealing the first, second and third films; and    -   e) cutting the films to produce a multi-compartment pouch.

The recess formed in step (b) may be achieved by applying a vacuum tothe compartment prepared in step (a).

In some embodiments, second, and/or third compartment(s) can be made ina separate step and then combined with the first compartment asdescribed in EP 2088187 or WO 2009/152031.

In other embodiments, pouches may be made according to a processincluding the steps of:

-   -   a) forming a first compartment, optionally using heat and/or        vacuum, using a first film on a first forming machine;    -   b) filling the first compartment with a first composition;    -   c) on a second forming machine, deforming a second film,        optionally using heat and vacuum, to make a second and        optionally third molded compartment;    -   d) filling the second and optionally third compartments;    -   e) sealing the second and optionally third compartment using a        third film;    -   f) placing the sealed second and optionally third compartments        onto the first compartment;    -   g) sealing the first, second and optionally third compartments;        and    -   h) cutting the films to produce a multi-compartment pouch.

The first and second forming machines may be selected based on theirsuitability to perform the above process. In some embodiments, the firstforming machine is preferably a horizontal forming machine, and thesecond forming machine is preferably a rotary drum forming machine,preferably located above the first forming machine.

It should be understood that by the use of appropriate feed stations, itmay be possible to manufacture multi-compartment pouches incorporating anumber of different or distinctive compositions and/or different ordistinctive liquid, gel or paste compositions.

EXAMPLES Example 1—Assays

p-nitrophenyl (pNP) assay:

The hydrolytic activity of a lipase may be determined by a kinetic assayusing p-nitrophenyl acyl esters as substrate.

A 100 mM stock solution in DMSO of the substrates: p-Nitrophenylbutyrate (C4), p-Nitrophenyl caproate (C6), p-Nitrophenyl caprate (C10),p-Nitrophenyl laurate (C12) and p-Nitrophenyl palmitate (C16) (all fromSigma-Aldrich Danmark A/S, Kirkebjerg Allé 84, 2605 Brøndby; Cat.no.:C4:N-9876, C6: N-0502, C10: N-0252, C12: N-2002, C16: N-2752) may bediluted to a final concentration of 1 mM 25 into assay buffer (50 mMTris; pH 7.7; 0.4% TritonX-100).

The lipase of the invention, the parent lipase and appropriate controls,e.g., Buffer (negative), Lipolase™ & Lipex™ (positive) in 50 mM Hepes;pH 8.0; 10 ppm TritonX-100; +/−20 mM CaCl₂ may be added to the substratesolution in the following final concentrations: 0.01 mg/ml; 5×10-3mg/ml; 2.5×10-4 mg/ml; and 1.25×10-4 mg/ml in 96-well NUNC plates (Cat.No:260836, Kamstrupvej 90, DK-4000, Roskilde). Release of p-nitrophenolby hydrolysis of p-nitrophenyl acyl may be monitored at 405 nm for 5minutes in 10 second intervals on a Spectra max 190 (Molecular DevicesGmbH, Bismarckring 39, 88400 Biberach an der Riss, GERMANY). Thehydrolytic activity towards one or more substrates of a variant may becompared to that of the parent lipase.

Relative Wash Performance (RP(Wash))

Washing experiments were performed using Automatic Mechanical StressAssay (AMSA) in order to assess the wash performance in laundry. TheAMSA plate has a number of slots for test solutions and a lid firmlysqueezing the laundry sample, the textile to be washed against all theslot openings. During the washing time, the plate, test solutions,textile and lid are vigorously shaken to bring the test solution incontact with the textile and apply mechanical stress in a regular,periodic oscillating manner. For further description see WO 02/42740especially the paragraph “Special method embodiments” at page 23-24.

The laundry experiments were conducted under the experimental conditionsspecified below:

Detergent: 3.3 g/L Detergent B Test solution volume: 160 uL Wash time:20 minutes Temperature: 30° C. Lipase dosage: 0 ppm or 0.35 ppm Testmaterial: Cream Annatto stained EMPA221 cotton textile prepared asdescribed in WO 2006/125437 except to exchanging turmeric with annatto(Annatto: A-320-WS, Chr. Hansen A/S, Boege Alle{acute over ( )} 10-12,DK-2970, Hoersholm, Denmark & EMPA221: EMPA, Lerchenfeldstrasse 5,CH-9014, St. Gallen, Switzerland) Water hardness was adjusted to 15° dHby addition of CaCl₂, MgCl₂ and NaHCO₃ (Ca²⁺:Mg²⁺:HCO³⁻ = 4:1:7.5).

Composition Detergent B wt % NaOH, pellets (>99%) 1.05 Linearalkylbenzenesulfonic acid (LAS) (97%) 7.20 Sodium laureth sulfate (SLES)(28%) 10.58 Soy fatty acid (>90%) 2.75 Coco fatty acid (>99%) 2.75Alcohol ethoxylate (AEO) with 8 mol EO; Lutensol TO 8 6.60 (~100%)Triethanol amine (100%) 3.33 Na-citrate, dihydrate (100%) 2.00 DTMPA;0.48 diethylenetriaminepentakis(methylene)pentakis(phosphonic acid),heptasodium salt (Dequest 2066 C) (~42% as Na7 salt) MPG (>98%) 6.00EtOH, propan-2-ol (90/10%) 3.00 Glycerol (>99.5) 1.71 Sodium formate(>95%) 1.00 PCA (40% as sodium salt) 0.46 Water up to 100

After washing the textiles were flushed in tap water and excess waterwas removed from the textiles using filter paper and immediatelythereafter the textiles were dried at 100° C. for 15 minutes.

The wash performance was measured as the color change of the washedsoiled textile. The soil was cream mixed with annatto. Annatto containsthe colorant norbixin, which function as a pH indicator by having pHdependent color change. Lipase activity leads to release of free fattyacids from the cream acylglycerols and this leads to pH decrease andthereby color change of the norbixin pH indicator. Lipase washperformance can therefore be expressed as the extent of color change oflight reflected-emitted from the washed soiled textile when illuminatedwith white light.

Color measurements were made with a professional flatbed scanner (EPSONEXPRESSION 10000XL, Atea A/S, Lautrupvang 6, 2750 Ballerup, Denmark),which was used to capture an image of the washed soiled textile. Toextract a value for the light intensity from the scanned images, 24-bitpixel values from the image were converted into values for red, greenand blue (RGB).

Color change due to lipase activity was measured as the change in thereflection-emitting of green light (G) relative to the light intensityvalue (Int) calculated as:

Int=√{square root over (R ² +G ² +B ²)}

The relative wash performance (RP(Wash)) of a lipase relative to areference lipase was calculated as:

RP(Wash)=(G/Int(variant)−G/Int(no enzyme))/(G/Int(lipase ref.) −G/Int(noenzyme)).

A lipase is considered to exhibit improved wash performance, if itperforms better than the reference (RP(Wash)>1). In the context of thepresent invention the reference enzyme is a lipase having a single aminoacid substitution relative to the tested lipase.

Odor Detection by Solid Phase Micro Extraction Gas ChromatographMeasurements.

The butyric acid release (odor) from the lipase washed swatches weremeasured by Solid Phase Micro Extraction Gas Chromatography (SPME-GC)using the following method.

Cream Annatto stained EMPA221 cotton textile was washed as specifiedabove and after wash, excess water was removed from the textile usingfilter paper and the textile was thereafter dried at 25° C. for 2 h.Each SPME-GC measurement was performed with four pieces of the washedand dried textile (5 mm in diameter), which were transferred to a GasChromatograph (GC) vial and the vial was closed. The samples wereincubated at 30° C. for 24 hours and subsequently heated to 140° C. for30 minutes and stored at 20° C-25° C. for at least 4 hours beforeanalysis. The analyses were performed on a Varian 3800 GC equipped witha Stabilwax- DA w/lntegra-Guard column (30 m, 0.32 mm ID and 0.25 um df)and a Carboxen PDMS SPME fiber (85 micro-m). Sampling from each GC vialwas done at 50° C. for 8 minutes with the SPME fiber in the head-spaceover the textile pieces and the sampled compounds were subsequentlyinjected onto the column (injector temperature =250° C.). Column flow =2ml helium/minute. Column oven temperature gradient: 0 minute =50° C., 2minutes =50° C., 6 minutes 45 seconds =240° C., 11 minutes 45 seconds=240° C. Detection was done using a Flame Ionization Detector (FID) andthe retention time for butyric acid was identified using an authenticstandard.

The relative odor release (RP(Odor)) of a lipase is the ratio betweenthe amount butyric acid released (peak area) from a lipase washed swatchand the amount butyric acid released (peak area) from a reference lipasewashed swatch, after both values have been corrected for the amount ofbutyric acid released (peak area) from a non-lipase washed swatch(blank). The reference lipase is a polypeptide having a single aminoacid substitution relative to the tested lipase. The relative odorperformance (RP(Odor)) of the polypeptide is calculated in accordancewith the below formula:

RP(Odor)=(odor(variant)−odor(no enzyme))/(odor(lipase ref.)−odor(noenzyme))

Where odor is the measured butyric acid (peak area) released from thetextile surface.

Benefit Risk Factor (RP(Wash)/RP(Odor))

The Benefit Risk factor describing the wash performance (Benefit)compared to the odor release (Risk) can be defined as RP(Wash)/RP(Odor).If the Benefit Risk factor of a lipase is higher than 1, the lipase hasbetter wash performance relative to the released odor compared to thereference lipase. Each of the result tables below represent a separateexperiment using the the reference lipase in the top most row designated“(reference lipase)” and setting the RP (wash), the RP(odor) and theRP(wash/Rp(odor) to 1 for the reference lipase. Performance of theremaining lipase variant in the separate experiment is then calculatedrelatively to the reference lipase for that experiment.
